On the subject of the Supercharger network, now over 1000 stations in the USA alone, we have had some discussion in the past about how well the network serves national parks, and similar places. In my home turf of the Four Corners states, I think the answer is "pretty well" — I put together a list of national parks and monuments below. This is "flyover country" so the Supercharger network is pretty sparse, compared to the coasts, where they seem to be everywhere. Nevertheless, around here the Supercharger access to national parks and monuments is good to excellent.
